The driver does not cope with the fact that probe can fail in a number
of cases after enabling runtime PM on the device; this results in
warnings about "Unbalanced pm_runtime_enable". Furthermore if probe
fails after invoking qcom_pcie_host_init() the power-domain will be left
referenced.
As it is not possible for the error handling in qcom_pcie_host_init() to
handle errors happening after returning from that function the
pm_runtime_get_sync() is moved to qcom_pcie_probe() as well.
Fixes: 854b69efbd ("PCI: qcom: add runtime pm support to pcie_port")
